lM PROVEM ENT IN LANTERNS.

Specification ibrniing part of Letters Patent No. 208,785, dated October 8, 1878; application filed September 6, 1879.

To all whom it may concern:

Be it known that I, GEORGE A. BEIDLER, of Philadelphia, in the county of Philadelphia, and in the State of Pennsylvania, have invented certain new and useful Improvements in Lanterns or Lamps; and do hereby declare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to that class of lanterns in which the air is taken in at or near the top of the globe, carried down at the sides thereof, and supplied to the burner; and the nature of my invention consists in the construction of fiues for conducting the air from the top downward to the burner; in a catch for holding the globe to one of the fiues; in the construction of the wick-tube and in the construction and combination of parts, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a central vertical section of a lantern embodying my invention. Fig. 2 is a bottom view of the basefor the globe. Figs. 3 and 4 show modifications of my invention, and Fig. 5 is a view of a detail.

A represents the oil-reservoir of a lantern. B is the burner, with wick-tube G. D is the base, attached to the burner, upon which the globe E is supported. F is the perforated top, which rests on the upper end of the globe. To the top F is attached a sort of dish-shaped vessel or chamber, G, having numerous perforations or openings a a in the upper side for the entrance of air, as shown.

The chamber G may or may not be closed at the bottom but preferably it is made so as to have only two outlets, which lead into two fiues, I and I, and these flues extend down close to or against the globe E to the lower end thereof, where they communicate with passages or fines H H, respectively, to conduct the air from the top to the burner.

The fines I I may be made of metal or any other suitable material, and run down either on the outside or inside of the globe. In either case the globe itself forms one side of each fine, while the fines proper may come in contact with the globe, as shown in Fig. 2, or

may have their edges inserted in grooves made in the globe, as shown at b b in Fig. 4.

The fiue I is connected to the fine passage or chamber H by a hinge, d, and the upper chamber, G, with the top F, is made fast to the upper end of said fiue I.

The fiue I may be made permanently attached to the passage H, and the top and chamber F G connected thereto by a springcatch, f, of any suitable construction.

In the bottom of the fiue I is a spring arm or latch, 71, upon which the globe E rests, and which holds the globe when the same is thrown to one side with the fiue I for lighting the lantern, thus retaining the globe in its place at all times.

It will readily be seen that the fiues I I conduct the air from the top down the sides of the globe to the burner, and said fiues, being made entirely independent of the globe, can be manufactured at but comparatively trifling cost.

The wick-tube O is at its upper end provided with inclined flanges i 1', as shown in Fig. 1, which break the force of the blast or air as it enters the burner to the flame; and while said flanges form no impediment or obstruction to the passage of the air, they prevent any flickering of the flame, which might be caused by a too sudden mingling of the current of air with the flame.

Wire guards J J may be applied to'this lantern, as shown, by connecting the same with flanged plates L L to fit over the fiues I I. These guards and plates are made entirely separate, and may or may not be used, as desired.

In lieu of the dish-shaped'chamber G, as above described, I may provide the top F with projecting flanges G G, as shown in Fig. 3, the lower one of said flanges having apertures to form connections with the fines.

In some cases I may provide the globeat its upper end with lugs m, extending partially around the same, as shown in Fig. 5, to form a support for the top and guide for the flues.

My lantern is, of course, to be provided with a bail, chain, or other derive for earryingand handling the same.

I am aware that lanterns are known where a closed cap or cover has been used over the globe, so as to revert the products of combustion through passages made in the bottom of the overlapping cap or eover.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, 1's- 1. In combination with the tines l 1, arranged in close contact with the globe, the airgachering chamber G at the npperpart of the globe, and having openings a a for conveying air down the flnes and the flue-passage H for conveying air to the flame, and the dome I with perforations to allow the exit of air, all substantially as set forth.

2. The combination of the hinged flue I, top F, with chamber G, stationary fine I, and a spring-latch, f, substantially as and for the purposes herein set: forth.

3. The spring-arm l'z,arranged in the lower end of the fine I, in combination with the globe E, for the purposes set; forth.

GEORGE A. BEIDLEH.
